Money is power and for you to get that power, you need to invest,save money. You don't wake up one day and get that power, it takes a lot of financial discipline to achieve that.so I suggest you save up and buy some bitcoins for the rainy days.
Bitcoin is one thing that will not lose value rather it appreciate in value. Just invest because at old age you will not have the strength to start doing all that you were doing when young.
We know that money is the root of all power in the present time, those who have money are able to do everything in life. Many times, people are not able to meet the financial needs of their family and relatives by working hard, where they constantly struggle. But those who do not lack money always live a luxurious life, rather they do not have to work. So if a hardworking person who works hard can save a small amount of money from that money and invest it in Bitcoin at some point, then it will be very useful for the future.
Especially in my opinion, those who work a lot at present, but still find it very difficult to manage their family, if they are old, they will not be able to work. So if they save a small amount of money while working and later invest it in Bitcoin and keep it, then it will definitely help them financially in their old age.
